 We have developed a new method for producing functional soft fibres under ambient conditions. This method involves the use of a special dope containing silver ions and polymer chains, which allows for the fibres to be formed without the need for solvents or other chemicals. These fibres are then able to be used for a variety of applications such as wearable electronics, sensors, and power generation.
